Investigations on the Calorimetric Method for Measurement of the AC Losses in Superconducting Tapes

The experimental determination of the AC losses in a superconducting material or structure has been of long-standing interest to the academic community. The purposes of the current experiments are to explore the influences of the position of temperature sensor heating time and limit temperature rise on the measurement results with the calorimetric method. The optimization heating time and the limit temperature rise of this method are obtained. The present results are beneficial for the more precise measurements of the AC losses in hightemperature superconducting materials and structures.
